丝氨酸蛋白酶在重要的生物、生理和病理过程中发挥着多种多样的作用。这些包括病毒、细菌和寄生虫感染、过敏性致敏、肿瘤侵袭和转移。基于活性的分析的使用已经成为确定丝氨酸蛋白酶在这无数过程中的精确作用的基础。已经开发了广泛的丝氨酸蛋白酶靶向的基于活性的探针(ABP)化学型,并且我们最近引入了生物素化的和“可点击的”肽,其含有P1 N-烷基甘氨酸精氨酸N-羟基琥珀酰亚胺基(NHS)氨基甲酸酯作为ABP,用于胰蛋白酶样丝氨酸蛋白酶的检测/分析。本研究提供了用于制备该ABP化学型的其他实例的合成细节,其作为其各自靶丝氨酸蛋白酶的有效不可逆抑制剂起作用。我们描述了它们用于广泛的丝氨酸蛋白酶,包括胰蛋白酶,胰蛋白酶样蛋白酶纤溶酶,胰凝乳蛋白酶,组织蛋白酶G,和中性粒细胞弹性蛋白酶(NE),包括后者的蛋白酶在从囊性纤维化患者的临床样本中的分析活性为基础的分析。
Serine proteases play varied and manifold roles in important biological, physiological, and pathological processes. These include viral, bacterial, and parasitic infection, allergic sensitization, tumor invasion, and metastasis. The use of activity-based profiling has been foundational in pinpointing the precise roles of serine proteases across this myriad of processes. A broad range of serine protease-targeted activity-based probe (ABP) chemotypes have been developed and we have recently introduced biotinylated and “clickable” peptides containing P1 N-alkyl glycine arginine N-hydroxy succinimidyl (NHS) carbamates as ABPs for detection/profiling of trypsin-like serine proteases. This present study provides synthetic details for the preparation of additional examples of this ABP chemotype, which function as potent irreversible inhibitors of their respective target serine protease. We describe their use for the activity-based profiling of a broad range of serine proteases including trypsin, the trypsin-like protease plasmin, chymotrypsin, cathepsin G, and neutrophil elastase (NE), including the profiling of the latter protease in clinical samples obtained from patients with cystic fibrosis.
